A method of forming a shaped abrasive particle including extruding a mixture into a form, applying a dopant material to an exterior surface of the form, and forming a precursor shaped abrasive particle from the form.
1. A particulate material comprising: a shaped abrasive particle having a body comprising a length, a width, and a thickness, wherein the body comprises a central region including the geometric center of the body having a first dopant material present in a center dopant amount (DCc), the body furthe
1. A particulate material comprising: a shaped abrasive particle having a body comprising a length, a width, and a thickness, wherein the body comprises a central region including the geometric center of the body having a first dopant material present in a center dopant amount (DCc), the body further comprising an upper surface defined by the dimensions of length and width, the upper surface having a second dopant material present in an upper surface dopant amount (DUSc), wherein the body comprises a dopant amount difference (ΔDc) between the center dopant amount and the upper surface dopant amount, and wherein the dopant amount difference (ΔDc) is at least about 0.2 wt % and not greater than about 30 wt %. 2. The particulate material of claim 1, wherein the first dopant material and second dopant material are different from each other. 3. The particulate material of claim 1, wherein the body comprises a two-dimensional shape as viewed in a plane defined by a length and a width of the shaped abrasive particle selected from the group consisting of polygons, ellipsoids, numerals, Greek alphabet characters, Latin alphabet characters, Russian alphabet characters, complex shapes having a combination of polygonal shapes, and a combination thereof. 4. The particulate material of claim 1, wherein the body comprises a material selected from the group consisting of an oxide, a nitride, a carbide, a boride, an oxycarbide, oxynitride, and a combination thereof. 5. The particulate material of claim 1, wherein at least one of the first dopant material and the second dopant material comprises an element or compound including an element selected from the group consisting of alkali elements, alkaline earth elements, rare-earth elements, hafnium (Hf), zirconium (Zr), niobium (Nb), tantalum (Ta), molybdenum (Mo), vanadium (V), and a combination thereof. 6. The particulate material of claim 1, wherein the body comprises not greater than about 12 wt % of the first dopant material for the total weight of the body and at least about 0.5 wt % of the first dopant material for the total weight of the body. 7. The particulate material of claim 1, wherein the body comprises not greater than about 12 wt % of the second dopant material for the total weight of the body and at least about 0.5 wt % of the second dopant material for the total weight of the body. 8. The particulate material of claim 1, wherein the upper surface has an upper surface contour significantly different than a contour of a bottom surface of the body as viewed in a cross-section of the body in a plane defined by the thickness and the length. 9. The particulate material of claim 1, wherein the body comprises a corner-truncated triangle shape. 10. The particulate material of claim 1, wherein the body comprises a pattern of features on at least one exterior surface, and wherein the features are selected from the group consisting of protrusions, grooves, ridges, scales, and a combination thereof. 11. A particulate material comprising: a shaped abrasive particle having a body comprising a length, a width, and a thickness, wherein the body comprises a central region including the geometric center of the body having a first dopant material present in a center dopant amount (DCc), the body further comprising an upper surface defined by the dimensions of length and width, the upper surface having a second dopant material present in an upper surface dopant amount (DUSc), wherein the body comprises a dopant amount difference (ΔDc) between the center dopant amount and the upper surface dopant amount, and wherein the body comprises not greater than about 12 wt % of the first dopant material for the total weight of the body and at least about 0.5 wt % of the first dopant material for the total weight of the body. 12. The particulate material of claim 11, wherein the first dopant material and second dopant material are different from each other. 13. The particulate material of claim 1, wherein the body comprises a two-dimensional shape as viewed in a plane defined by a length and a width of the shaped abrasive particle selected from the group consisting of polygons, ellipsoids, numerals, Greek alphabet characters, Latin alphabet characters, Russian alphabet characters, complex shapes having a combination of polygonal shapes, and a combination thereof. 14. The particulate material of claim 11, wherein at least one of the first dopant material and the second dopant material comprises an element or compound including an element selected from the group consisting of alkali elements, alkaline earth elements, rare-earth elements, hafnium (Hf), zirconium (Zr), niobium (Nb), tantalum (Ta), molybdenum (Mo), vanadium (V), and a combination thereof. 15. The particulate material of claim 11, wherein the body comprises a corner-truncated triangle shape. 16. A particulate material comprising: a shaped abrasive particle having a body comprising a length, a width, and a thickness, wherein the body comprises a central region including the geometric center of the body having a first dopant material present in a center dopant amount (DCc,), the body further comprising an upper surface defined by the dimensions of length and width, the upper surface having a second dopant material present in an upper surface dopant amount (DUSc), wherein the body comprises a dopant amount difference (ΔDc) between the center dopant amount and the upper surface dopant amount, and wherein the body comprises not greater than about 12 wt % of the second dopant material for the total weight of the body and at least about 0.5 wt % of the second dopant material for the total weight of the body. 17. The particulate material of claim 16, wherein the first dopant material and second dopant material are different from each other. 18. The particulate material of claim 16, wherein the body comprises a two-dimensional shape as viewed in a plane defined by a length and a width of the shaped abrasive particle selected from the group consisting of polygons, ellipsoids, numerals, Greek alphabet characters, Latin alphabet characters, Russian alphabet characters, complex shapes having a combination of polygonal shapes, and a combination thereof. 19. The particulate material of claim 16, wherein at least one of the first dopant material and the second dopant material comprises an element or compound including an element selected from the group consisting of alkali elements, alkaline earth elements, rare-earth elements, hafnium (Hf), zirconium (Zr), niobium (Nb), tantalum (Ta), molybdenum (Mo), vanadium (V), and a combination thereof. 20. The particulate material of claim 16, wherein the body comprises a corner-truncated triangle shape.
